ORAL PATHOLOGY: SALIVA and its physiology

Physiology& Saliva content
Normal daily production is 1-1.5L
Water 99,5%
Organic compounds – mucin, amylase, lysozym, immunoglobulin A
Anorganic compounds – HCO3-, I, K, Cl, Na, Ca, phosphates and others.
About 45% is produced by the parotid gland,
45% by the submandibular glands,
and 5% each by the sublingual and minor salivary glands.
Saliva is produced at a low basal rate throughout the day, with flow increasing 10-fold during meals. Saliva functions to maintain lubrication of the mucous membranes and to clear food, cellular debris, and bacteria from the oral cavity.
